Tritex multigauge 3000 UW thickness gauge
The Multigauge 3000 Underwater gauge is a simple, robust ultrasonic gauge designed for most common underwater thickness gauging applications. It has been designed and built to survive extremely harsh conditions that exist in the offshore and underwater industries worldwide. LED display ensures the display can be seen by the diver, even in poor visibility. Measurement can be made without removal of the coatings.
Features:
- ignores coatings using multiple echo
- pressure tested to 500 m.
- bright clear LED display
- easy to use
- no fuss upgrade option to a topside repeater
- rugged and robust
- intelligent probe recognition (IPR)
- automatic measurement verification (AMVS)
- no zeroing required
Complete kit comprising gauge, membranes, rechargeable battery, charger, o-rings, molykote grease, carry case, membrane oil, manual.

TRITEX MULTIGAUGE 3000 UW THICKNESS GAUGE WITH COMMUNICATER SOFTWARE AND 100M CABLE
The Multigauge 3000 Surface Software displays measurements onto a laptop which allows the topside person to log the data as required. The kit is supplied with an RS232 to USB converter for connection with most laptop computers. The software allows the user to adjust settings in the gauge through a bi-directional link, display the repeated measurements from the diver and datalog the measurements into useful templates.
Features:
- Displays real time measurements from the Multigauge 3000
- Easy to install and very user friendly
- Datalogging with grid or string templates, or a combination of both
- Bi-directional to allow settings in the gauge to be changed
- Accepts RS232 or RS422 input
- Time, date and a label can be added to each measurement value
- Common output interface (.csv).

TRITEX MULTIGAUGE 3000 UW THICKNESS GAUGE WITH SURFACE DISPLAY UNIT AND 100M CABLE
The surface display unit and 100 M. cable are attached in this package. With this package the measurements can be verifyed at the surface, by either a class surveyor or supervisor. The Surface Display Unit has bi-directional communication with the Multigauge 3000. This means that settings can be adjusted in the Multigauge 3000 without having to break the ‘O’ ring seals. Also, settings can be adjusted whilst the diver is underwater using the Multigauge 3000 Underwater Thickness Gauge.
Features:
- Bi-directional communication with the Multigauge 3000
- Displayed measurement
- Remaining battery life
- Echo signal strength
- Calibration data
- Probe type being used

Whatever the application, Tritex have a gauge suited specifically for it. The rugged designs not only look good but are also durable. All probes have IPR (Intelligent Probe Recognition), which automatically adjusts settings in the gauge at the same time as transmitting recognition data - the result is a perfectly matched probe and gauge for enhanced performance. That's not all; the AMVS (Automatic Measurement Verification System) ensures only true measurements are displayed, even on the most heavily corroded metals. Housed in purpose designed cases and incorporating Triple Echo to completely ignore coatings, Tritex Multigauges are the choice for the future...
The Multigauge 5600 is a simple, robust ultrasonic thickness gauge designed for most common thickness gauging applications. The easy to use keypad allows operator interface whilst the bright LCD display can be used in all light conditions. The moulded soft rubber surround feels comfortable, looks good and provides extra protection against knocks and scrapes.

Combined Underwater Photometer/Radiometer System (UPRS) and Underwater Flux Meter (UFM)
This instrumentation package is designed to enhance the integrity of sub-sea MPI by enabling measurement of magnetic field strength, ambient visible light, and ultra-violet irradiance with a single sub-sea module. It has been proven over several years service in the North Sea and elsewhere.
In practice, it allows the user to replicate previous work-face MPI conditions on subsequent inspections, thus reducing the probability or spurious or missed indications. Initial inspections benefit from using a known and measured set-up.
An improvement on earlier versions, the HCL unit has a single flying lead to a combined probe head -this contains the UV and visible sensors, together with the magnetometer probe. This reduces the number of both penetrators and trailing cables.
Power is from internal Nickel Cadmium cells, which will give in excess of 20 hours continuous use, recharging taking about 12 hours from 'Battery Low' indication. The charging circuitry has been enhanced to give effectively penetratorless charging, the stainless steel switch knob being used as one contact and the grab-ring the other. Internal electronics double-isolate these contacts to ensure that no current can flow OUT of them, thus preventing both external discharging via the contacts and damage from charger misconnection. Additionally, a fuse has been incorporated within the battery pack that provides protection against both short circuits and excessive charging currents.
Total safety is therefore ensured, and the elimination of a waterproof connector for charging provides cost and reliability advantages to the user.
The display is a 12.5mm back-lit Liquid Crystal, and ranges are selected by a rotary switch. This switch has no detents, and no end-stops, thus minimising the potential of damage by abuse. The selected range is clearly shown by indicators on the unit, as is the 'Low Battery' condition.
The magnetometer is a surface magnetometer, working on AC fields and is generally thought to be the only type of device that will measure the field below the surface of the parent metal. Other devices, such as Burmah-Castrol strips and Hall-effect magnetometers can only detect the field above the surface of the metal, and this will vary significantly with proximity. By requiring a physical contact with the workface, and only measuring the field within the parent metal, the HCL magnetometer reduces the potential for inadvertent operator adjustment of the readings by manipulating the device in place of adjusting the field current. Calibration is traceable via NAMAS certified test pieces.
The photometer/radiometer is a custom marinisation of the well-known instrument from Levy Hill Laboratories. Levy Hill calibrates each unit to standards traceable to the United Kingdom's National Physical Laboratory.
The housing is machined from solid aluminium alloy, hard anodised to Defence Standard 03-26/2. It is fitted with a stainless steel 'grab-ring' that serves to protect the port, penetrator and switch knob, and provides a handle, a tie-off point and the negative charging electrode. The grab-ring is sacrificial, and in cases of severe impact is designed to deform and absorb the shock, thus protecting the pressure hull.
Use of this instrumentation will allow diving contractors to ensure consistent standards of MPI, and it's specification by structure operators will provide them with additional confidence in MPI results.
